  • the uppermost contact surface portions 78 of the projections 70 and 72 are closer together than the lowermost contact surface portion 80 since the terminal-receiving housing 31 is more resilient at the upper wall 51 than at the lower wall 52.
  • the distance between the two uppermost male terminal contact surface portions 78 is about 2% to about 10% shorter than the distance between the lowermost male terminal contact surface portions 80 so that the pressure of the uppermost contact surface portion 78 and the lowermost contact surface portions 80 against the male terminal 30 will be approximately the same.
  • the uppermost male terminal contact surface portions 78 are closer together than the lowermost male terminal contact surface portions 80 to take into account the greater resiliency of the upper portion of the female terminal 20 because of the greater dimension of the seam or slit 46 extending completely across the upper wall 66 defining an upper portion of the male terminal receiving cavity 31.
  • the male terminal 30 is more resilient toward an uppermost portion of the contacting side walls since the male terminal 30 does not have an upper structural wall.
  • the difference in dimensions between the uppermost contact surface portions 78 and the lowermost contact surface portions 80 can be varied depending upon the thickness of the female terminal walls 62, 64, 66, and 68; the difference in the length of upper and lower slits 46 and 54; and the outer dimensions of the male terminal 30 with respect to the inner dimensions of the male terminalreceiving cavity 31 of the female terminal 20.

  • the female terminal 20 is inserted into the housing 12 from right toward left as shown in FIG. 3 so that the spring tabs or lances 82 are slightly compressed when the female terminal 20 is received within the housing 12 as the lances 82 pass an inner shoulder 86 (FIG. 3).

  • the female terminal 20 includes one or more alignment dimples 107 in longitudinal alignment with the laterally extending projections 70 or 72 in the sidewalls 62 and 64 and spaced therefrom to maintain alignment of the male terminal 30 within the female terminal 20 so that the male terminal 30 does not fit closer to either sidewall 62 or 64 but is maintained in central longitudinal alignment within the female terminal 20.
  • the female terminal 20, at the front end 32 can be formed having slits 106 and 108 in sidewalls 62 and 64 extending toward the rear end 34 of the female terminal and ending at the laterally extending projections.
  • two distinct and sharply pointed laterally extending projections 110 and 112 are formed in sidewall 62 and two distinct, sharply pointed laterally extending projections 114 and 116 are formed in sidewall 64 to provide high pressure contact of the points 118, 120, 122 and 124 against the male terminal 30. Similar to the construction shown in FIG.
  • the points 118 and 122 are spaced a smaller distance than the points 120 and 124 to provide equalization of contact forces of all four points 118, 120, 122 and 124 against the male terminal 30 since the slit 46 in the upper wall 66 extends completely longitudinally across the upper wall 66 forming a portion of the male terminal receiving cavity and the lower slit or seam 54 extends only partially across the lower wall 52 forming a portion of the male terminal receiving cavity 31.

  • the distance between projections 130 and 134 is less than the distance between projections 132 and 136 to compensate for the greater resiliency at the top of the ellipse than at the bottom of the ellipse because of the difference in the lengths of the slits 46 and 54.
  • the male terminal 30, like the female terminal 20 is formed from flat metal stock including two upwardly turned sidewalls 138 and 140 integral with a lower or bottom wall 142 to form a generally U-shaped male terminal dimensioned to fit within the cavity 31 of the female terminal 20.

Further, the lower wall 142 is bent to curve upwardly in a smooth arc to form a lower plow member 162 (FIG. 10) so that the lower surface 142 of the male terminal does not have any sharp edges which might make more difficult the insertion of the male terminal 30 into the female terminal 20.
  • electrical connection between the male terminal 30 and the female terminal 20 can be made with relatively low insertion forces while providing a relatively high pressure electrical contact between the male terminal 30 and the female terminal 20 due to the sharp contacts and resilient terminals.
